Patent DE-3810681-A1 (DE)
Inventor: KIENLE UDO
IPC: A23L27/10
Filed: 1988-03-29
Abstract: It is known to use parts of Stevia rebaudiana plants or extracts or isolates obtained therefrom and enzymatic transformation products as sweeteners. The introduction of these sweeteners is prevented in European and American cultural circles by an extraneous taste or aftertaste which is not sweet. All purification processes which have been developed to date and can be carried out on the industrial scale give products retaining this upsetting taste. It is possible according to the invention to remove the concomitant substances which have an upsetting taste from parts of the plant or known extracts and the further processing products thereof by extraction with a supercritical gas, carbon dioxide being the preferred extractant for practical reasons. Preparation of sweeteners for foodstuffs and beverages on a natural basis.

Title: Female connector strip having suppression filters
Inventor: SCHILL ROLF DIPL ING
IPC: H01R13/719
Filed: 1988-04-28
Abstract: In the case of a female connector strip (1) having suppression filters (5), which connector strip (1) has only a small structural height, is used especially for mounting on printed circuit boards (30) and can be removed easily for repair, the metallic housing (2) has an H-shaped cross-section. An insulating body (3), which holds the female contacts (4), and a protective strip (7), which centres the connecting tabs (6) of the female contacts (4), are inserted into the holders (13, 14) formed on both sides of the baseplate (15) and are fastened to one another by means of threaded bolts (26) and nuts (28). The insulating body (3) and protective strip (7) have U-shaped cross-sections and lie in the holders (13, 14) with the open sides directed towards the baseplate (15), as a result of which the tubular suppression filters (5), which are soldered by means of the outer foil into the baseplate (15), are covered. The inner foil of the suppression filter (5) is soldered to the female contact (4) which has been plugged through. Its female connection body does not fill the suppression filter (5) completely and a space (27) thus remains into which a ferrite bead can be inserted if required. <IMAGE>

Patent DE-3833947-A1 (DE)
Title: Solar hot-air balloon, and a method for producing its supporting body
Inventor: STIEFEL GOTTFRIED ALFRED
IPC: B64B1/58
Filed: 1988-10-05
Abstract: In the case of conventional hot-air balloons, heavy gas bottles must be carried in order to produce the hot air. There is a considerable risk of fire when the burner is operated particularly with respect to the combustible envelope of the hot-air balloon, whose range is linked to the capacity of the gas bottle or bottles carried. The novel solar hot-air balloon is intended to overcome the disadvantages of conventional hot-air balloons. In particular, the risk of fire is intended to be reduced to a minimum, and the range of the solar hot-air balloon is intended to be independent of the quantity of gas carried. The supporting body is essentially formed by a translucent envelope made of plastic film with a reflector. The reflector extends over a subregion of the envelope, preferably in the lower region of the supporting body. The supporting body is equipped with a maneouvring valve which blows out horizontally, as a result of which positioning and braking maneouvres can be carried out, and the solar hot-air balloon can even achieve a certain amount of propulsion. <IMAGE>

Patent DE-3930667-A1 (DE)
Inventor: WAGENBLAST GERHARD DR
IPC: G03G5/024
Filed: 1989-09-14
Abstract: In a new process for reversible or irreversible production of an image by the photographic effect of energy on a recordng layer in the presence or absence of an electrical and/or magnetic field, a pattern of surface charges corresponding to the photographic effect of energy is produced on the surface of the recording layer. The recording layer contains or consists of a vitreous organic material which has permanent dipoles and zero or negligible photoconductivity. The surface charge pattern is produced, with little or no formation of free charge carriers, by reversible photographic alignment of all or some of the permanent dipoles present in the recording layers. The new process is advantageously carried out with a new appliance which comprises a suitable recording element, devices for obtaining the photographic effect of energy on the recording layer of the recording element, and a counter-electrode in direct contact with the recording layer and which can be separated from the latter. The surface charge pattern produced by the new process can be treated with liquid or solid toners. The resulting toner image can then be fixed on the recording layer or transferred from the recording layer to another surface. The surface charge pattern can then be erased by the action of energy over the entire surface. It is thus possible to produce photocopies without using the high-voltage sources required for conventional electrophotographic processes.
